Moose Tracker is a free online musical instrument: a music tracker plus a full synthesizer, in your browser. Design sounds with analog and FM synthesis, filters, envelopes and a sampler, starting from 147 presets. Write songs in the pattern editor or piano roll, and play live on the Jam keyboard. No install or sign-up. Imports MIDI, MOD, XM, S3M and IT; exports WAV and Ogg. Plus an MCP server, so AI assistants and tools can render, convert, describe and make sound effects from your songs.
